ADJUSTABLE STOCK POWER GRINDER AND PULPER.

Specification of Letters Patent.

Patented Mar. 1, 1910.

Application filed .Tuly 13, 1907. Serial No. 383,670.

To all whom it may concern:

Be it known that I, JonN Snufrnnr, of the village of llfiiinipegosis, inthe Province of Manitoba, Canada, have invented certain new and usefulImprovements in Adjustable Stock Power Grinders and Pulpers, of whichthe following' is the specification.

My invention relates to machines for grinding and pulping roots, and theobject of the invention is to provide a cheap, serviceable device,adapted for both roots and grain, by which the animals when feedinggrind or pulp their own food, and it consists in the construction andnovel combination of parts hereinafter fully described, illustrated inthe accompanying drawing, and pointed out in the claims hereto appended;it being understood that various changes in the form, proportion, sizeand minor details of construction, within the scope of the claims, maybe resorted to without departing from the spirit or sacrificing any ofthe advantages of the invention.

In the drawings z- Figure l. is a perspective View of my completeinvention, parts being broken away for the sake of clearness. Fig 2 is avertical sectional view through the center of my device. Fig. 3. is ahorizontal sectional View, the section being taken in the plane asdenoted by the line X X, Fig. Q. Fig. 4. is a plan view of a modifiedform of hopper, which is employed. Fig. 5. is a plan view of a pulpingplate used with the modified form of hopper. Fig. G. is a detailedvertical sectional view through the latter hopper and pulping plate, inposition on the vertical shaft of the device, the section being taken inthe plane as denoted by the line Y Y, Fig. Il.

In the drawings like characters of refierence indicate correspondingparts in each figure.

l is a suitable base of any form, carrying centrally a vertical shaft orspindle Q, having at or near the top a cross arm for a purposehereinafter explained.

l is a lower circular feed tray or table having an upturned side or rimas at 5, such tray being rotatable around the shaft, and may besupported by a collar secured to the shaft by a thumb screw (3 orpreferably by a set of hooked arms attached to the cylinder on the trayas hereinafter described.

7 is a cylindrical shell or drum constituting a feed receptacle andcarried by the tray, such shell or drum being opened at the top andbottom and having a series of similar openings S of a triangular outlinearranged therearound at or near the bottom.

fl is a cylinder surrounding the above cylindcr and having rectangularopenings l0 therein at the bottom registering with the opening S.

ll are propelling wings cut and turned from the material of the cylinderitself, such wings passing' obliquely from the base of the cylinder, asclearly shown in Fig. 3. l have found it preferable to form these wingsin this wisc, but they may be separately attached if desired.

l2 arc slots in the outer cylinder through which an adjustable screw 13passes to the inner cylinder. By loosening the screw the outer cylindercan be turned on the inner cylinder and the passages or openings 8closed to a greater or less extent as will be readily understood.

The wings l1 have their outer tips rounded to present a smooth andharmless edge.

lst is a hopper adapted to rest on the upper edge of the inner cylinderwith its bottom within the cylinder.

l5 are apertures in the bottoni of the hopper through which the materialmay pass to an upper bur 't6 screwed to the hopper bottom.

17 is a lower bur operating in conjunction with the upper bur andfastened on a block of wood 18, which has a cross slot in the lower facefor the reception of a pin 19 passing' through the shaft, and rigidtherewith. The pin is bent as shown in Fig. 2 of the drawing. in orderto allow the bur to oscillate slightly so that small stones 0r harmfulforeign matter in the grain may pass through without injury to the burs,which control the supply of feed to the rotary cylinder' or receptacleand the annular feed tray.

2O is a flat cross spring supported within the hopper passing' freelythrough its sides.

2l is a bolt passing centrally through the spring and ha ving thereon atthe upper end, nuts and at the lower end an eye 93 to receive a U-shapedarm Q-l passing downwardly, and secured to the cross rod 3 on the shaft.The tension spring is provided in order that the surface pressure on theburs may be adjusted, such being done by screw- Yone at either side ofthe center.

ing down the nuts 23 thereby pressing the upper bur on the lower.

34 are hooked arms, having their upper ends threaded to receive a nut8st', and are provided to inter-connect the ends of the spring 20 withthe sides of the shells 7. This `is done simply by passing the hookedend of of the base, when no shoulder 6 is used.

This as before suggested is the preferable way for supporting the trayand cylinder, as the whole weight of the grain being ground is directlycarried by the bur wheels. By adjusting the nuts on the arms the traycan be raised or lowered above the base.

25 is a deflector or cone arranged around the shaft and within thecylinder resting on the tray 4.

26 is an agitator or rod having its upper end passing through t-he shaftand the body extending downwardly over the central cone. The rod isadjustable out and in from the shaft by two nuts 27, one at either sideof the shaft, and by unscrewing one nut and screwing up the other theposition of the agitator from the face of the cone is determined.

In using the above described device the grain is placed in the hopper,there having been previously some grain thrown to the bottom of thecylinder near the openings.

The reason for putting the grain primarilyin the cylinder isso thatanimals will have, at the onset, a certain amount of grain to feed from,and when eating the food from the openings 10, as the amount distributedon the tray Adecreases the tendency is for them to strive to get more.In doing this both the cylinders are rotated by their effort on thewings; and this same movement grinds the grain falling on the burs. Inthis manner as long as they feed the cylindersare continuously rotated,and consequently the animals grind their own food.

I have found that the device is particularly adapted to the feeding ofhogs, as their rooting propensities are especially strong.

In connection with the device I supply a second attachment especiallydesigned for the grinding and pulping of roots. This second attachment Ihave shown in the drawings in Figs. 4, and 6, and will now proceed todescribe. QS is a hopper of practically the same form as 14 save that itis completely open at the bottom. 29 is a cross bar supported within thehopper, having an opening 30 centrally therethrough and carryingdownwardly extending cross knives or blades 8l, 32 is a cir cular platehaving perforations 32 with cutting edges or points more or less in theform of a sieve or grater. The bottom of the hopper rests on thecircular plate and in this position the knives 9;] just clear thegrating projections. is a sleeve passing centrally through the plate 32and adapted to iit the shaft The lower end of the sleeve is cut away toreceive the cross pin lf), and the upper end passes through the opening30 in the cross bar, in this wise centering the bar` To use theattachment the burs and the hopper are removed and the circular plate isplaced in practically the same position as the burs occupied, and thehopper QS is placed over the plate and retained thereon by the crossspring 20, in the same manner as-the other hopper. In operation theroots are placed in the hopper and its rotation causes the roots to bescraped over the grating plate, the knives forcing them against theplate. The grated material passes through the apertures 32 and is fed tothe animals in a like manner as hereinbefore described.

I have found in actual operation very little effort is required on thepart of the stock to revolve the feeder, and that the stock take theirfood slower than when feeding from troughs, still getting all theyrequire, with little chance for waste.
